Residential Building Inspector Practice Exam

The minimum bar size and spacing for vertical reinforcement of an unsupported wall can be found in Table R404.1.2(2) of the building code. This table provides specific requirements that are crucial for ensuring the structural integrity of walls, particularly in relation to lateral loads and the overall stability of the building. It details not only the bar sizes but also the necessary spacing, which helps prevent issues such as cracking or structural failure due to inadequate reinforcement.

The particular focus of this table is on the design parameters necessary for unsupported walls, making it the correct source. Understanding the requirements laid out in this table is vital for inspectors, as they ensure that construction meets safety and performance standards. Other options may reference different aspects of building materials or standards but do not specifically address the reinforcement of unsupported walls in the same way as Table R404.1.2(2).
